Letters Paz-mt No. 87,575, dated M11/mh 9, 1869.

'The Sr-hedule referred to in these Letters Patent and making. part of the same.

Ta all whom it may concern Be it known that I, EUGENE CHARLES MALDANT,

a citizen of Paris, in the Empire of France, have invented certain new and useful Improvements in Gas and Steam-Regulators; and I do hereby declare the following to be a full, clear, and exact description of' the` saine, reference being had to the annexed-drawing, making part of this speciicati'on, and iu which is illustrateda vertical longitudinal-section of saidV regulator.

The object lof my invention is to insure a steady flow of gas or steam from from the boiler, generator, reservoir, or ometer, to and through the service-pipes and burners, which object I accomplish as follows; that is to sav- I introduce the steam or. gas into a receiving-pipe, A, 4set in the lower part of a metal chamber, and the upper end of this pipe I tit into a cone-shapedvalve and seat, substantially in the manner shown by D.

The said chamber, H, I cover with a second chamber, or cap I, through the top of which I pass the valve-rod F, to which is attachedl the valve D,and on the top of said cap I, and under a screw-nut on said valve-rod, I arrange a spiral spring, R, to assist the operation of the valve.

Under the cap I, and on the valve-stem, or rod, I arrange a cap, L, the lower flange of which I'attach to the upper put of the chamber H, by means of a dexible connection, E, consisting of India rubber, leather, or other suitable fabric, substantially inthe manner shown. v

The chamber H is also tted with a general servicepipe, B, upon which there is a number-of jet-pipes, or burners, shown by J.

Now, the operation of the regulator is as follows:

The valve is n'rst adjusted to the desired position by means ofthe screw R, and the cap L and flexible connection E are screwed up to resist the required pressure. The steam or gas is then let into the pipe A, and continues to ow, in a steady stream, up around the valve, into the chamber C and service-pipe B, to supply the jetsJ, and the regulator, as long as the pressure of the gas or steam remains uniform, will remain inactive, but as soon as the pressure of steam or gas is increased in the boiler or olneter, or too large a supply let in, the cap L will be forced up, and the valve partially closed; or in case one of the jet-pipes or burners be shut oif, by which the consumption of gas or steam through the outlet is partially stopped, the pressure in the chamber C will be increased, the Valve partially closed, and 'so on, thus'regulating the flow of gas'or steam, and maintaining a uniform pressure in' the service-pipe.

l Having now described the nature and extent of my invention, i y

, I claim, and desire to secure by Letters Patent The new and useful manufacture, consisting of a gasand steam-regulator, constructed substantially in the mannerfdescribed.
